Please can anyone out there in intelligent land tell me why after building this circuit,(attached) that in the off state & with the slave socket unloaded there is still main potential across live & neutral? if you put a small load i,e a 15 watt lamp across L&n the main potential disappears is there a floor in the circuit or am i going to have to leave a lamp connected at all times?
Any assistance appreciated.
B/c :( :( |

I think you got your answer in Note 2 (the very last bit of the text).
You can meassure the main across the L and n with a high resistance meter, but you will not ne able to draw any current (like your 15W lamp) |

Thanks for the reply but there is another dilemma! the neon in the slave socket that is connected also stays on in a no load state indicating power at the socket, when lets say my dvd player is connected it switches in & out of standby although this could be due to the fact that the on switch is in the secondary side,
Is there any way to stop the neon lighting, or replace it with a mains wired led

Sorry but I don't know this circuit...
Maybe someone else can help you ;) |

There are two possible reasons
One path is the RC across the triac
The second is the dc resistance of the triac. This will be about 1Mega ohm.
Try measuring the triac resistance out of the circuit, using a DMM.
The triac will be false triggered by noise on mains and this circuit is a bad idea to connect to a DVD. A simle solution will be a mains rated relay on the master supply.
Try connecting a high value resistor across the socket.
